If you come for Ariana Grande, you’d best be ready for her to come right back, sis. After Grammys producer Ken Ehrlich spoke with the Associated Press about Grande pulling out of this Sunday’s ceremony, Grande clapped back on Twitter, calling Ehrlich out for “lying about” her.

Grande tweeted a screenshot of the interview, in which Ehrlich is quoted as saying that “when we finally got the point where we thought maybe it would work, she felt it was too late for her to pull something together for sure. And it’s too bad. She’s a great artist. And I’d love to get her in the show this year.”

“i’ve kept my mouth shut but now you’re lying about me,” Grande tweeted on Thursday. “i can pull together a performance over night and you know that, Ken. it was when my creativity & self expression was stifled by you, that i decided not to attend. I hope the show is exactly what you want it to be and more.”

Grande claimed that she offered the Grammys three different song options and that her choice not to perform was about “collaboration. it’s about feeling supported. it’s about art and honesty. not politics. not doing favors or playing games. it’s just a game y’all ... and i’m sorry but that’s not what music is to me.” Period.

Grande added that she’s “grateful for the acknowledgement” but couldn’t help adding a zinger about the irony of her tweets’ timing: “passed a Grammy’s bus with my face on it typing those.”
